Serious problem with my Dual Channel RAMs

[DABhand]

Sure were still friends, its called a debate nothing bad about that.

But, I do have my own PC shop and it doesnt matter what programs etc tell you, when using your memory to the max the speed will drop to 166. Trust me on that, ive been using debuggers etc and ive seen the memory speed drop.

64 bit boards are better at handling data transfer, so can use 200mhz speed, but on 32bit boards most (not all) will drop speed to 166. No matter what POST says.

Thank God for Intel, my 2 X 512mb PC3200 dual channel is running at 201MHz and that's confirmed in Sisoftware Sandra.

Mainboard Gigabyte 8IK1100(standing in for my 8KNXP), CPU FSB 200MHz(P4 3200MHz).

and my nForce 2 has the RAM running in 200MHz, trust me it does...

A good example to explain it better would be this...


You see a skinny guy giving people hassle on the street, you walk up thinking "Skinny guy not a problem ill just knock him out"

You go over to punch him, he turns round picks up a car and squashes you with it..

You go "Damnnnn Deceptively strong"


Moral: Appearances can be deceptive :P

Hrmm.... Yes something like that... Buuuuut not in this case...

Well Kosmiq i will have to put down the fact ive been an Engineer for a long number of years, and know how things work.

It doesnt matter what Sisoft Sandra or any of these other programs say, they arent telling you in detail how the speed of the memory is fluctuating within a given time frame. All that they usually report is the speed located on the memory chips rom's.

There is good debugging software out there that can report the current speed of memory. Perhaps looking for those, and you will get a suprise

Well Sisoft Sandra and the like reports the speed the memory are currently running at.

Like this:
Setting the memory to run at 166MHz Sandra will show (to your surprise) 333MHz DDR. OMG how did that happen? No idea.
Setting the memory to run at 180MHz will result in? OMG 360MHz DDR as reported by Sandra, POST and even nVidia System Utility (that can be used for windows overclocking btw)
Setting the memory to run at 200MHZ will give the correct result... Guess what? 400MHz DDR how can that be? No idea must be magic somehow... All apps reports the same.
Setting the memory to run att 225MHz will give 450MHz output no matter what the checking utility is...

So there is either magic going or all apps will show wrong.
Please give me the name of a good debugger that will show me the info you say me to look at and I will gladly test it and give screenshots.

Sorry for being a little negative there, no pun intented just felt like writing like that...
